Hi!
You're greatly determined and clearly willing to learn. The snotty-nosed nay-sayers are depressing and increasingly I'm avocating people to turn themselves into a Frayed Knot (see
https://www.organmatters.co.uk/index.php?topic=268.0 for what this really means) because in order to survive, people have to be flexible and not boring. On
look at all those boring people in the audience waking up and discovering that they don't have to be boring and that they can engage with people and have fun.
End of rant. Sorry. You have enthusiasm and it's a great shame to see people put you down.
Buy a Korg OT120 tuner. With it you'll be able to tune unequal temperaments such as I tuned recently for an experimental session:

There's also a programme called TLab97 which can run on a laptop that is great.
You need two tuning wedges (I use paps wedges) and a tuning lever.
Set A first. Put two wedges to blank off the two outer strings of the triplet. With a paps wedge, the two prongs will do it with the one wedge. Always let down the string before you bring it up again. This means first that you check you have the right string and second that it doesn't snag on the agreff or bar. Bring the string up to pitch in a smooth pull. Make sure that you don't lever the pin backwards and forwards, that it's kept upright. Having got the string up to pitch, experiment with small adjustment to see how the string behaves - if you bring it up to pitch and do nothing, perhaps the section near the tuning peg is at a higher tension than the sounding part of the string. So you might have to gently relax it. Play the string hard to see of the vibrations shake the tension through. Having done one string, proceed to the two on either side and make sure that they are tuned to the centre one EXACTLY. No beating. No premature decay of the sound.
With the tuning meter you can do every string likewise. But after the central octave having set the scale, listen to the string that you're tuning and as well as the meter, check it against the note in the central octave. You must wedge off the spare two strings so that you're hearing just one string against one string. There should be no beats. When you get to two octaves above middle C, set the tuner to 441 instead of 440. This will start to stretch the octaves at the top, and be prepared to accept that top notes are tuned percussion rather than notes. Often the notes beat - the string can emit two notes very close together at once. These notes are hell. For the top octave or two octaves, the TuneLab programme can help mor accurately than the Korg tuner.
Bottom two octaves. Tune these both to octaves as well as making sure they sound nice as tenths - an octave and a third. The tenth should sound sweet. When you're experienced, in unequal temperaments, you can tune the bass notes so that their harmonics are in tune with pure intervals in the temperament -
explains a bit about these pure intervals.
There's really not a lot more to tuning than this other than practice - doing it.
When you come to retune your piano, don't stick to 440 - find what most of the strings are in and do it to whatever it is. You want to avoid moving more strings than you need to - and if you do this then your piano will increase in stability over the years. As a result of this philosophy, the piano we use for concerts
can withstand Beethoven and Prokofiev without going out of tune. Often I simply go through the instrument looking for "odd man out" strings - where two are in tune with each other and one is out, then you just need to tune the one that's out to the two that are together.
I hope this helps and gives you the encouragement that you deserve.
Best wishes
